Serial No. 608,918.

To all whom it may concern:

Be it known that I GARRETT M. VROOME, a citizen of the Unitec States,and a resident of the city of New York, West New Brighton, borough ofRichmond, in the county of Richmond and State of New York, have inventeda new and Improved Line-Holder, of which the following is a full, clear,and exact description.

My invention relates to a new and improved form of line holder for usein shingling roofs and at other localities where it is desired to markoff a series of parallel lines.

An object of my device is to provide a means whereby a series of linesmay be marked off across a surface by operating on one side only of thesurface.

A further object of my invention is to operate the device from adistance, whereby the marking line may be changed from one location toanother without the necessity of making trips across the marked surfacein order to regulate or actuate the marking device.

A still further object of my invention is to provide a device wherebyone end of the line may be held in position across the roof or otherobject which it is desired to mark, and then be released, which actionwill cause it to automatically swing to another position, and again to athird position, without the necessity of approaching the device in orderto change the location of one end of the line.

With the above and other objects in view, as will more fully hereinafterappear, the present invention consists in certain novel details ofconstruction and arrangement of parts hereinafter fully described,lllustrated in the accompanying drawings, and more particularly pointedout in the claims.

Reference is to behad to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures, and in which Figure 1 is aperspective View of a roof showing a preferred embodiment of myinvention attached thereto; Fig. 2 is a plan view showing theline-carrying device in its first position, and in prolonged dottedlines showing the carrying arm in its second position and in fine dottedlines showing the carrying arm in its third or final position; Fig. 3 isa side elevation of the device shown in Fig. 2; Fig. 4 is a transversesectional view taken on the line 44 of Fig. 3 and looking in thedirection of the arrow; and Fig. 5 is a detailed perspective viewshowing the locking block.

As shown in the figures, my device comprises a frame 1, preferably ofmetal having an overhanging hood or casing 2, within which is disposedthe mechanism of my device, and having a rear wall 3 from opposite sidesof which project horizontally-disposed brackets or lugs 4 and 5. Thebracket 5, which will hereinafter be referred to as the rear bracket haspositioned thereon beneath the hood 2, a two-part clamp 6, between theparts of which is positioned a slidable gage rod 7 having graduations 8thereon, the outer end of which rod is bent downwardly to form aprojecting point 9, which point is adapted to engage with the endshingle 10, as shown in Fig. 1, whereby the marking device may bedefinitely and rigidly affixed in position. The forward lug 4 hasmounted thereon a block 11, from which projects an integral stud 12constituting a bearing for a line-carrying arm 13,said stud, above saidarm, being square in horizontal cross-section, upon which square partfits a lock block 14, the arm 13 and block 14 being held in position onthe stud 12 by means of a binding screw 15. The line-carrying arm 13 ispreferably made of two parts welded together, a part 13 which projects aslight distance from the stud 12 and a graduated arm 16, referably ofsquare crosssection upon which slides a square sleeve 17 held inposition by means of a set-screw 18. On the under side of the sleeve 17is an eye 19, through which passes a chalking line 20 extending from theside of the roof or other surface opposite the side to which the deviceis attached, through the eye 19 to a knob 21 extending upwardly from oneend of a lever 22 pivoted to the part 13 between the stud 13 and theupwardly-projecting shoulder 23 formed by the members 13 and 16. The endof the lever 22, o posite the end to which the line 20 is attac ed, isbent toward the stud 12 and is formed into a sharp pointed nose 24,which nose is adapt ed to engage in one or the other of V-shapedrecesses 25 positioned about the out-er edge of the block 14 at an angleof ninety degrees to each other.

Projecting from the lever 22 adjacent the fulcrum point 26 is a pin 27carrying a pivoted arm 28, said arm having a longitudinal slot 29therein, through which slot is bent one end of a coil tension spring 30,which spring extends lengthwise of the device beneath the hood 2, havingits opposite end permanently fastened to a stud 31 extending upwardlyfrom the clamp 6. As this spring is fastened at one end to the stud 31and the other end is attached to the lever 22 offset from its fulcrumedpoint, it will be seen that the tendency of this spring is to Withdrawthe head 24 of the lever out of engagement with the block 14, while anypull on the line 20 will act against the pull of this spring to hold thehead of the lever 24 in engagement with one of the recesses in the block14', thereby holding the arm 16 in the full-line position shown in Fig.2, or in the right-angle position shown in dotted lines in Fig. 2, or inthe completely-folded position, also shown in dotted lines in Fig. 2,beneath the spring.

In operation, thedevice is set in position, as shown in Fig. 1, thepointed end 9 en with the surface and the entire device positioned bysliding the same along the rod 7 after which the device is held inposition by means of a binding screw 32, and the arm 16 is swung intoposition, as indicated in Figs. 2 and 3. Then the sleeve 17 is movedalong the arm 16 from the pivot a distance equal to the distance desiredbetween successive parallellines, and the sleeve is tightened in thisposition by means of the screw 18. It will then be seen that from theopposite side of the surface the operator by pulling on the line 20,causes the lever 22 to engage' with the fixed head 14, thereby holdingthe arm in extended position against the action of the spring. Releasingthe tension on the line 20, the spring is free to act, thereby drawingthe arm 16 around into a position at right angles to its initialposition, as shown in dotted lines in 2; then tension upon the line20will pull the lever 22 intoengagenient with the second notch and inthis, position another line may be struck; again releasing the lever 22,the springj30' will draw the arm' 16 into it final posit-ion arallelwith the frame 1, when a third line may be struck, I L

, It will be seen that by this construction, the operator may place thedevice upon the edge of a surface and without. again appreaching thesame, it is possible to strike three parallel lines in succession, afterwhich the device may be set for three more lines, and so on along theentire surface to be marked.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:
